While we strive to publish as many interesting new open data for TWIST as possible, it is worth taking a look at already existing open data. In this post we would like to give you a brief outlook over the crowdsourced open data from the application «Züri wie neu». We think that there are still some hidden, so far undiscovered, truths to be found.
«Züri wie neu» is an online platform of the Zurich city administration in order to facilitate the reporting of damaged infrastructure by citizens. It went online in 2013. Since then it is moderated by the city administration and managed transparently with all – anonymized - reports available as open data.
The open dataset derived from «Züri wie neu» currently contains around 14’000 reports (!). It includes the exact georeferenced location of the infrastructure damage, the time of recording, the exact description, the categorisation, the processing status and the time when the report was completed. For approximately 1’700 messages, even transmitted photos can be referred to it. All data is available in open geo formats and can also be queried via the open interface Open311. Open311 is an open standard (GeoReport v2), which is used internationally by numerous other cities, such as e.g. Bonn, Toronto or Lisbon. This makes the data comparable with other cities.
It is obvious that the spatial and temporal components of these data usually invite for geo analysis and cartographic visualisations, such as heatmaps or animated maps. Here is an example of an animation which shows all new entries by citizens in 2017.
